Just for you Earthling, so your not confused. I came into I.T in 1984 as an engineer. This was in the days when systems engineers looked after the hardware, and the operating systems on various platforms, and when Engineers looked after the hardware only, and Software engineers looked after the operating systems and Applications. So we had various flavors of system generation disks, and this is how the operating system talked to the hardware. I started as a hardware engineer, and then a systems engineer. Normal career progression. Lots of engineers have taken this route. ( nothing special, just application and hard work, and a lot of fun ). Then in the 1990's we got various flavors of UNIX, it existed in the 1960's, but in the 1990's it became a commercial offering. This was a step change. The reason was we never had system generations any more. The operating system would talk to the hardware, through something called the shell, which was an interface between the operating system and Kernel. All built into the operating system. So you could no longer just have hardware engineers. In order to fix a broken piece of hardware, you couldn't just replace it, as often it wouldn't work. You had to delete the old definitions from a command line and rebuild it, otherwise wouldn't be recognized. So we created support People who could do all this. The I.T Technical Analyst was born. I was lucky to be in the right place at the right time. We went on to become involved in Pre Production in Research and development center's , as when new kit came out, we had to be ready to implement and teach from day 1. We also did Technical Bulletins and prepare courses and lectures, mainly for customers, in pre sales and also educating system administrators. We also had to get involved with Application software, as the kernel had to be changed, in order to get the best out of the Application, and sometimes make it work. This is called Kernel tuning. Then we get Virtual engine technologies, and that means we now have a hypervisor that can configure the hardware, and partition mainframes. So when I say I am an engineer. I really am an engineer. I hope this goes somewhere to clearing up your confusion on the subject. Basically, if you have a question for me, just ask, I won't be offended. But can we quit the snide comments. Many thanks.
